You know the minds of 50 odd million people?
Why else would they believe it? Why would they believe something with no evidence? A large proportion of the American population has brought into the cult of Trump, which is supposedly anti politicians, anti Washington etc.
I mean I read 10 years ago over 40% of Americans think Jesus will return to earth before 2050, does that mean we need to address their concerns too?
Some people are just idiots. America is susceptible to worshipping individuals as the whole Trump movement has shown.
